Answer: See below
Explanation:
Solve this system of equation using elimination method:
3x - y = 0
2x - y = 1
________
3x - y = 0
-1(2x - y = 1)
_________
3x - y = 0
-2x + y = -1
_________
X = -1
We know that x = -1 now let’s plug it in the one of the equation to find y:
2x - y = 1
2(-1) - y = 1
-2 - y = 1
-y = 3
y = -3
Answer:
The answer is 3 meters.
Step-by-step explanation:
Suzy has 4 saplings the distance between two of the is 3/4
So if the distance from one to another is 3/4 then you have to do 3/4 (.75) times 4. Giving you the answer of 3 meters.
C is the correct answer I believe
Answer:
The second boat will catch up in 8.5 hours, and they will be 187 km from their port.
Step-by-step explanation:
Since the system of equations are d=18t+34 and d=22t, you first rewrite d=18t+34 as an equation. 18t+34=22 and that equals to 8.5=t. Then you solve the next one d=22t and the answer you got from the other equation, you substitute d=22(8.5) and that equals to 187.
